Answer:
The quotient is x² + 6x +3
Remainder = -1
Step-by-step explanation:
<u><em>Explanation:-</em></u>
Given Polynomial equation
f(x) = x³+5x²−9x−7
By using synthetic division
<em> x = 2 </em> 1 5 -9 -7
<u> 0 1 12 6</u>
<u> 1 6 3 </u><em><u> -1 </u></em><u> </u>
The quotient is x² + 6x +3
Remainder = -1
Answer:
We know that:
1 inch in the drawing, equals 3 feet in the real room.
Then if the scale is 6 in by 4 in, the actual room is:
6*3ft by 4*3ft
18ft by 12ft.
The total area of the room is:
18ft*12ft = 216ft^2.
Now we know that the price of the carpet is $5,50 per square ft,
The area of the room is 216 ft^2, then if we want to carpet the whole room, we need to pay 216 times $5.50.
Cost = 216*$5.50 = $1,188
Answer:
x = - 1
Step-by-step explanation:
y = 4 is the equation of a horizontal line parallel to the x- axis and passing through all points with a y- coordinate of 4
A perpendicular line is a vertical line parallel to the y- axis with equation
x = c
where c is the value of the x- coordinates the line passes through
The line passes through (- 1, 1) with an x- coordinate of - 1, thus
The equation of the perpendicular line is x = - 1
